I knew the price that was given me 6 weeks ago was to much
My guess was $130s or so
.NAMBA20...Caterpillar UL-1, P-Spec OM29, P-Mono DF33, P-Spec JAE, Aussie 33" Hydro-LSH, Sprintcat CC2028 on 8s, PT SS45 Q Hydro, PS295 UL-1 power, OSE Brothers Outlaw QMono 4-sale, Rio 51z CC2028 on 8s
how would i make water cooling jaket for this motor?
Yep.............and $149, plus a very minimal shipping price and to your door in 3 days
OR............$136, higher shipping price for standard shipping..........WAY longer to get it..........or Higher dollar EMS and still longer to get it.............
No brainer..........................and he backs up his product better than anyone..........responds to e-mails...........etc..............
You guys think 1340kv on 6s will get him 60mph? I think thats a good combo and would power the boat well but I think he might need to up the cell count a bit to get that kind of speed out of a 36" boat...
I think others would be a lot more qualified to answer what would be correct. I am just thinking that everything I've ever got that kind of speed out of Ive had to turn more rpm than that, but I could be wrong.
That motor doesn't need more rpm, because it should have enough torque to spin a huuge prop! That is where you're speed will come from.
Ok thanks so thats going to be my set up now i need to know esc and hardware
i was thinking 180amp esc and this hardware http://www.offshoreelectrics.com/pro...prod=ose-80085
Not on 6S right off the bat. On 7S he has more rpm and thats most likely where he might have to settle. 8S is just about suicide with that motor as amp spikes would almost certainly get over 300 no problem. But on 6S, and taking the time to dial in the hull, perfect a prop, there is no reason 60's is not possible. The gas/nitro folks are doing it with 23 to 27k rpm motors. No reason us FE types cannot duplicate such on 29k.

Change is the one Constant
So if I was to get a 1090KV version, 6S would be enough with 24,200 rpm... 22.2 x1090 = 24,198 rpm...
Or would I be better with 7S?
Please let me know, it is for the 40" DF clone mono. ... Using Monster 2000 esc....

It seems like that would be enough rpm with a big prop. Remember that these motors claim to be 90% efficient, so you have to subtract 10% right away plus anywhere from 10-20% for slip. Also remember that that number is unloaded rpm. Without knowing how this motor will perform, I would stay on the higher rpm side. Either 7s or the 1340kv version on 6s.
Here is a link for the ose top speed page where you can play with the numbers to get a good speed estimate for you're build. http://www.offshoreelectrics.com/conversion.htm
O.k., thanks! What prop can you suggest to start with and beyond...?

My gut is telling me to go 8S on 1090Kv for some reason?, thats alot of power though...
Need to do allot of thinking because I don't want to get the wrong batch of cells...

What props can you turn?
Nortavlag Bulc
What do you think of the 1340 kv on8s
Steve's 1090kv's are selling faster so far.
Nortavlag Bulc
The 1090 is a more 8s friendly motor.
I would run the 1090 on 6s with 1/4" drive components and a monster prop.
Thats odd, is one post somewhat contradictory to the other?
I've got 1/4" hardware, step down stub to3/16", (thanks Steve!)
Just can't decide.... 6,7 or, 8S ?
Nortavlag Bulc
I meant 8s is better suited for the 1090 as opposed to the 1340. I like 4 to 6s setups myself. That statement was in response to 08gtrking. Guess I shoulda quoted him.
Thats more like it.
Yes but, I want to nip at some other more expensive Open Mono's heels.
